Order of operations

• To find the factors, write down all possible pairs of whole numbers that multiply to give the given number.
• A factor is one of the numbers that make up a product.
• The product is the result when two numbers are multiplied together.
• The product is found by multiplying the two numbers together.
• Factors can be found by dividing the number into equal groups or finding the prime factorisation.
• Prime factorisation involves breaking down a composite number (a number with more than two factors) into its prime factors.
• When we say "a" goes into "b", it means there's no remainder left over from dividing b by a.
• Division is an operation where we split something into parts.
• When we have an expression involving brackets, we need to work out what's inside first.
• We use BIDMAS as a guide to working out which operation to do next.
• To divide, we find how many times one number fits inside another.
• We use BIDMAS as a guide when working out expressions with different operators.
• Brackets are used to group things together.
• Brackets are always done first.
• Indices tell us how many times to repeat multiplication.
